St. Athanasius

Oh! My brethren, how shall we admire the loving-kindness of the Saviour? With what power, and with what a trumpet should a man cry out, exalting these His benefits! That not only should we bear His image, but should receive from Him an example and pattern of heavenly conversation; that as He has begun, we should go on, that suffering, we should not threaten, being reviled, we should not revile again, but should bless them that curse, and in everything commit ourselves to God who judges righteously. – Saint Athanasius, Letter 2.5
